Re: X10 problems
Hi Adam
I had a similar problem with X10 signals not getting through to their
destination.
In my situation I found it was my TV putting interference on the ring
main. Moving my CM12U to a socket closer to the controlled devices
fixed my problem - but I had the advantage that I don't need the
computer permanently connected to the CM12U.
Can I suggest the following :
1) Unplug every mains device in your house. Tedious but the only way
to isolate the problem.
2) Test your X10 setup - if it now works you know you have a
"dirty"
device that is putting interference on the mains. The challenge now
is to re-plug your devices one by one until you find the offender.
3) If your X10 setup still doesn't work switch off lighting
circuits/cooker circuits etc. at your fuse box so leaving only the
ring main connected. If X10 still doesn't work you may be getting
interference from a neighbour... You will need a friendly neighbour
to investigate their appliances! Also I think there is a filter that
you can connect to clean your mains supply as it come into your house.
If and when you find the offending appliance you can get a mains
filter from Laser that will prevent interference travelling from the
appliance into the ring main.
Good luck!
